How does the USPTO communicate defective papers in ex parte reexamination?

The USPTO uses specific forms to communicate defective papers in ex parte reexamination, depending on who requested the reexamination. According to MPEP 2296, there are two forms for this purpose:

  • PTOL-475: Notice of Defective Paper In Ex Parte Reexamination – Third Party Requested
  • PTO-2311: Notice of Defective Paper in Ex Parte Reexamination – Patent Owner Requested

These forms are used to notify the relevant party when a submitted paper in the reexamination proceeding is found to be defective, allowing them to correct the issues and ensure proper processing of the reexamination.
